UNITED STATES PATENT OFFICE..

WILLIAM It. HILDEBRAND, OF CHICAGO, ILLINOIS.

RADIATOR.

Application filed May 7,

dated in, substantially, the spaces hereto-r fore found between the ordinary steam radiator sections whereby my present improvement will not take up any more room than said steam radiators, and whereby, also, the air to be heated and set in motion will be placed in more intimate contact with the walls of the steam passages and thus be more rapidly heated thereby.

And with the above named objects in view my present invention consists ot' the novel construction, combination and arrangement l of parts hereinafter referred to in detail and more particularly pointed out in the appended claims.

Figure l is a perspective view ot a radiator embodying` my invention.

Figure- 2 is an enlarged perspective view of one of the interior sections.

Figure 3 is an enlarged horizontal ction through several broken away interior sections.

Figure 4 is a section taken substantially on the line 4-4 ot Figure 2.

Figure 5 is a similar view of one ot' the end sections, taken substantially on the line 5-5 of Figure 2.

In the several views 2 and 3 are the end sections and these. are similar to the intermediate sections with the exception that said end sections are closedv by an outside wall 3. An end section'must also have a capa cious air inlet. The intermediate sections oi Figures 2, 3 and 4 are, respectively, designatedby the numeral 4, and each is substantiallyalike at both sides. From the opposite outer side ot each sections steam chantiber projects a seri-es of ribs or flanges 5, 6, 7 and 8, which, when placed against similar formations on adjoining sections, form an air-chamber. The flanges 5 and 6 are connected by a. curved bottom flange 9 and a 1921. Serial N0. 467,654.

top flange l0, the latter having cutaway portions or semi-bores 11, l2 and 13, which when placed opposite portions of an adjoining` flange l0, t'orm air outlets 14 that lead from air-spacesl. i

Each radiator section has the usual interior steam-space 16 with hubs 17 and 18, which when abutting adjoining hubs close the air-spaces to the steam spaces. The end section hubs 18 are connected with the source oi' steam supply by suitable and ordinary Fittings provided with a valve 19. The steam space l@ is bridged by a web or wall 2O with a slot 2l therethrough which places adjoining air spaces in communication with each other.

The radiator sections are clamped together by the usual bolt-rods 22, 28, and 24, and as a unit have their air-spaces provided with a capacious air-inlet, or mouth-piece, 25.

I claim as my invention 4l. A radiator composed of integral sections each having a hollow steam-space and interior and exterior projections adapted to be placed against similar projections on ad jacent sections to form inclosed air-spaces, a steam-inlet and .outlet common to all ot the sections, an air-inlet common to all of said sections and a plurality of air-outlets for each oit said sections.

2. A radiator composed ont sections, each section having a steam-space and a pair of air-spaces to be closed by similar air-spaces on adjoining sections, means securing all ot said sections together to form a radiator unit, a steam-inlet and an air-inlet common to all of said sections, and a plurality of airpassages leading from the top ot each ot said air-spaces to the outer air.

3. The combination with a radiator composed ot sections having hollow steamfspacc interiors open to each other, ot a series ot' projecting ribs on the opposite sides ot' each section and adapted to abut against similar ribs on adjoining' sections to torni air-spaces, each ot' said air spaces having a plurality ot' airoutlet passages in the 'top oi the radiator, channels through said stean'i-spaces which place said air-spaces in communication with each other, and an air-intake common to all orp said air-spaces for cach oi said air-spaces.

In testimony whereof I have hereunto signed my naine.

IVILLIAM It. HILDEBRAND.
